net: fix suspicious rcu_dereference_check in net/sched/sch_fq_codel.c
commit 46e5da40ae (net: qdisc: use rcu prefix and silence sparse warnings) triggers a spurious warning: net/sched/sch_fq_codel.c:97 suspicious rcu_dereference_check() usage! The code should be using the _bh variant of rcu_dereference.
